- How do we use sample results to estimate values of population parameters?

- What are the best point estimates of the population proportion "p", population mean "μ" and standard deviation "σ"? Why?

- How accurate is the sample result of 85% likely to be?

- Given that only 1,007 people were polled in the population of 241,472,385 adults, is the sample sample size too small to be meaningful?

- What is a critical value? How is it related to the confidence level?

- What is the Student t distribution?

Suppose we are interested in how well people do on a standardized test when they take it for a second time. In a random sample of 400 students who took the test for a second time, students gained an average of X-bar = 12 points. Let’s say that the sample comes from a population with σ = 42. The 95% confidence interval for μ (the mean point gain) is: μ = 12 ± (1.96) (42/√400) = 12 ± 4.12 =...

1.The sample mean is an unbiased estimator for the population mean. This means: The sample mean always equals the population mean. The average sample mean, over all possible samples, equals the population mean. The sample mean will only vary a little from the population mean. The sample mean has a normal distribution. 2.Which of the following statements is CORRECTabout the sampling distribution of the sample mean: The standard error of the sample mean will decrease as the sample size increases....

4) The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of...

It is extremely urgent!!!!!!!!!!!!!!!!!!!!!!!! --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- BIOETHICS. Bioethics as a field is relatively new, emerging only in the late 1960s, though many of the questions it addresses are as old as medicine itself. When Hippocrates wrote his now famous dictum Primum non nocere (First, do no harm), he was grappling with one of the core issues still facing human medicine, namely, the role and duty of the...
